The Instructions accompanying this Letter of Transmittal should be read carefully before completing this Letter of Transmittal. This Letter of Transmittal is for use only by registered shareholders. Shareholders whose common shares are registered in the name of a broker, investment dealer, bank, trust company, trustee or other nominee should contact that nominee for assistance in depositing those shares and should follow the instructions of such nominee in order to deposit their shares. LETTER OF TRANSMITTAL to accompany certificates for shares of common stock of MIDAS GOLD, INC. This Letter of Transmittal is for use by registered holders ("Shareholders") of shares of common stock ("Midas Shares") of Midas Gold, Inc. ("Midas") in connection with the proposed plan of share exchange (the "Plan") involving Midas and Midas Gold Corp. ("Midas Canada"), pursuant to which, subject to receiving all required approvals and the satisfaction of certain closing conditions, all of the issued and outstanding Midas Shares will be acquired by Midas Canada. Pursuant to the Plan, each Midas Share will be transferred by the holder thereof in exchange for one (1) common share (a "Midas Canada Share") in the capital of Midas Canada (the "Exchange"). The Plan forms part of a series of transactions contemplated under the combination agreement dated February 22, 2011 among Vista Gold U.S. Inc., Idaho Gold Resources, LLC ("Idaho Gold"), Midas and Midas Canada whereby Midas' and Idaho Gold's respective assets, namely their mineral properties located in the Stibnite-Yellow Pine mining district located in Valley County, Idaho, would be combined (the "Combination"). Shareholders are strongly urged to read the proxy statement of Midas (the "Proxy Statement") accompanying this Letter of Transmittal, delivered in connection with the special meeting of Shareholders to be held on April 1, 2011 (the "Meeting"). Capitalized terms used but not defined in this Letter of Transmittal that are defined in the Proxy Statement have the meanings set out in the Proxy Statement. It is anticipated that the Combination and the Exchange will be completed on or about April 6, 2011. If the Combination and Exchange are completed, then, at the Effective Time, Shareholders (other than Dissenting Shareholders) will be entitled to receive, in exchange for each Midas Share held, one Midas Canada Share. IMPORTANT NOTICE In order to receive Midas Canada Shares in exchange for their Midas Shares, Shareholders are required to deposit the certificates representing the Midas Shares held by them with the Depositary at the address specified below. This Letter of Transmittal, properly completed and duly executed, together with all other required documents, must accompany all certificates for Midas Shares deposited for payment pursuant to the Exchange. Shareholders who do not deliver the certificates 2 representing their Midas Shares and all other required documents to the Depositary on or before the sixth anniversary of the Effective Date: (i) will lose their right to receive Midas Canada Shares in exchange for their Midas Shares; (ii) will not own any interest in Midas or Midas Canada; and (iii) will not be paid any cash or other compensation in lieu thereof. See "Cancellation of Rights after Six Years" in the enclosed Instructions. The Exchange will be immediately taxable to a Shareholder who is resident in Canada for the purposes of the Income Tax Act (Canada) (the "Tax Act"), unless such Shareholder files a tax election form (duly executed with Midas Canada) with the Canada Revenue Agency and any applicable provincial tax authority by the applicable deadline, in which case a full or partial deferral of tax under the Tax Act may be obtained. If you are (i) a registered shareholder who is also a beneficial shareholder or (ii) an intermediary who represents a beneficial shareholder, who qualifies as an "Eligible Holder" (as such term is defined in the Proxy Statement) you may request a tax election package by completing Box E in this Letter of Transmittal. As described in detail in the Proxy Statement, Midas Canada will not be responsible for the proper completion or filing of any tax election and the electing Shareholders will be solely responsible for the payment of any taxes, interest, expenses, damages or late filing penalties resulting from the failure to properly complete or file a tax election in the form or manner and within the time prescribed by applicable tax legislation. Midas Canada agrees only to execute any properly completed tax election and to forward such election by mail to the applicable Shareholder by the 90th day after the receipt thereof by Midas Canada provided that any such tax election is received by Midas Canada within 90 days following the Effective Date. See "Certain Canadian Federal Income Tax Considerations" beginning on page 23 of the Proxy Statement. A tax election package, consisting of the relevant federal and provincial tax election forms and a letter of instructions will be available online at www.midasgoldinc.com following the Effective Date and on request made by checking the appropriate box in Box E in this Letter of Transmittal will be separately distributed to you. The completion of a tax election is complicated and Eligible Holders should consult their own legal and tax advisors in order to properly complete a tax election in the appropriate circumstances.
